A detailed analysis of the process of two-photon emission by an electron scattered from a high-intensity laser pulse is presented. The calculations are performed in the framework of strong-field QED and include exactly the presence of the laser field described as a plane wave [1]. We investigate the full nonlinear quantum regime of interaction with a few-cycle pulse, where nonlinear effects in...

We obtain analytical solutions of the Dirac and the Klein-Gordon equations coupled to a strong electromagnetic wave in the presence of plasma environment. These are a generalization of the familiar Volkov solutions. The contribution of the non-zero photon effective mass to the scalar and fermion wavefunctions, conserved quantities and effective mass is demonstrated for the first time. The new...

We investigate fermion production in space- and time-dependent electric fields in 1+1 dimensional QED using real-time lattice techniques. We compute the non-equilibrium time evolution of gauge invariant observables and investigate the decay of the field due to the backreaction mechanism. The latter allows us to discuss the striking phenomenon of a linear rising potential building up between...
